ios - 动态 UITextField 创建

Question

是否可以创建动态UITextField，例如当用户单击文本字段进行编辑时，它会自动UITextField在UITextField.

Answer 1

创建一个新的文本字段，如：

UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(75,210,265,30)];
myTextField.placeholder=@"Enter Label Here";
myTextField.font =[UIFont systemFontOfSize:25];
myTextField.clearButtonMode=UITextFieldViewModeWhileEditing;
[self.view addSubView:myTextField];

您需要根据您的要求更改框架。

Answer 2

只需将此代码添加到您的 .m 文件中，或者只需在您的textFieldShouldBeginEditing:方法中添加以下代码

 - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
    UITextField *txtTemp=[[UITextField alloc]initWithFrame:CGRectMake(yourTextField.frame.origin.x, yourTextField.frame.origin.y + 50, yourTextField.frame.size.width, yourTextField.frame.size.height)];
    txtTemp.delegate = self;
    [self.view addSubview:txtTemp];
    return YES;
}

Answer 3

是的。这里在

-(void)textFieldDidBeginEditing:(UITextField *)textField

UITextField根据原始框架分配另一个UITextField，如果要添加多个文本字段，请将分配循环。希望这可以帮助。

Answer 4

实施UITextFieldDelegate

- (void)textFieldDidBeginEditing:(UITextField *)textField{    

      if(textField == firstTextFeild){

          //Create secondTextFeild.
   }

}
